OF-MAINE METAL sroon" Application filed November 8, 1930. Serial No. 494,356.

This invention relates to a metal spool which is of general utility but which is particularly adapted for' use in the wire in- V dustry.

It is the general object of. my invention to provide a sheet metal spool of an lmproved construction, so designed that it may be easily and economically manufactured and that it will be strong and reliable in use,

My invention further relates to arrangements and combinations of parts'which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. l is a sectional side elevation of my improved spool; and 7 Figs. 2 and 3 are end views, looking in the directions of the arrows 2 and 3 in Fig. 1.

Referring to the drawing, my improved spool comprises a tubular sheet metal barrel 10, a tubular bearing member 11 and apair f of sheet metal heads. I will first describe the I construction of the head shown at the left in Fig. 1.

This head comprises a disc 14 having an outwardly displaced portion 15 which provides an annular shoulder 16, closely fitting within one end of the tubular barrel 10. The displaced portion 15 is reversely oflset at its middle portion to provide a sleeve 18, closely fitting the outside of the tubular bearing member 11. V

A second disc is provided with a peripheral flange 21 fitting within a corresponding flange 22 formed on the outer edge of the disc 14. The discs 14 and 20 are preferably secured in assembled relation by spinning the edge of the flange 22 inwardly over the periphery of the disc 20, as indicated at 24.

The disc 20 has a hole 25 at its center, aligned with the opening in the tubular bearing member 11. Preferably the, inner edges of the disc 20 partially cover the endof the tube 11, as indicated in Fig. 1.

The head shown at the right in Fig. 1- is similar to the head previously described but the outer flange of the disc 32 is contracted in its middle portion to form a peripheral groove, adapted to receive a rope or belt which might be used for frictionally re 'sist ing rotation of the spool. The grooving of p the outer flange 30.necessitates acorresponding inward contraction of the inner flange '34,

so that the parts may be assembled,

At the right hand endof the spool I have i also shown provision for driving the sp'ool. For this purpose the tubular bearing member 11 is provided with opposed slots 40, and the disc 42 is provided withradially extending slots 43,aligned with the slots 40. This permits the insertion of a driving shaft having a cross bar or cross-pin for engagement with rotated. 1 r

Inassemblingthe spools, the tubes ld'fand 11 are inserted in the discs 14 "and 32 and are preferably secured therein by spot-welding at the points A. The discs 20and 42 are then secured in place bythe spinning operation previously described;

LWhile I have shown the spool as having a plain head at one end and a grooved head at the other, it will be understood that spools may be'manufactured within the scope of my invention in which both headsare plain or both heads are grooved and in which either or both heads are grooved and in which either or both ends of the spool may be provided with the slots and 43. V i

While my improved spool is of general" utility and is adapted to many different purposes by reason of its exceptionally strong and rigid construction, the spool. possesses particular advantages in the wire industry, as wire wound thereon may be subjected to an annealing process while still on the spool and withoutrewinding, as has been the common practice heretofore. The rigid sheet metal construction enables the spool towithstand the annealing temperature without inury. p Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, other- 1. A sheet metal spool comprising a tu'bul lar barrel, a tubular bearing member, and

sheet metal heads each having a portion,

. axially displaced to provide an annular shoulder closely fitting in an end of said tubular barrel, with said displaced portion inslots aligned With said radially extended slots said tubular bearing member and'ex'tending Wardly ofi'set at its center to provide an annularsleeve closelyfitt-ing over saidtubular bearing member, each head being formed of inner and outer discs spaced apa'rtand provided With overlapping concentric peripheral flanges, one of said outer discs having 3 radially extended slots and the corresponding end portion of the tubular bearing inernber-having longitudinally extended driving in'the associated outer end disc.

2. 'A sheetimet-al spool comprising a tubular barrel, a tubular bearing member, and

sheet metal heads each formed of inner and outer discs'held in spaced relation by overlapping peripheral flanges thereof, one of said discs having a central portion axially offset to provide anannular shoulder closely fitting in an end of said tubular barrel, one

inner part of said oifset portion -being dis placed axially in' the opposite direction to provide an annular sleeve closely fitting over toward theoute'r end thereof, said annular shoulder and said annular sleeve beingdisposed in the sameradial section of said spool.

whereof I have hereunto
